1.1 ioee'r.

Our invention relates to improvements in uncoupling devices of that class which are mounted on railway cars so that they can be operated to release the locking device of a coupler without requiringthe brakeman to go between the cars. 1

One of the objects of the invention is to provide an uncoupling device of simple construction, comprising only a few parts which are assembled in a novel manner to prevent the surreptitious removal thereof and yet permit a separation of parts without damage to the device if the coupler head is accidentally pulled away from the car body.

, Heretofore' the railroad companies have suffered considerable annoyance and expense by reason of the theft of parts of the uncoupling devices, and. this is' particularly true when those devices are used which comprise links and clevises secured by cotter When the uncoupling device is rendered useless in this manner it becomes, necessary for th brakeman to enter between the cars to couple or uncou le them, which involves great risk. Anot er disadvantage of the uncoupling devices heretofore used is that they are so assembled and connected with the locking device that the coupler or locking device cannot beremoved from the car without disconnecting vtheunconpling device also, and if the- I coupling device of few parts of simple and in expensive construction, which canbe readily applied to a car and easily operated, and which embodies a separable connection to avoid damage to the device in event of an Specification of Letters Patent. pp i .fl Kay 2 19 2 s rial no cat129- lfatented Sept. 19rd.

And a further objeet of the invention is to dispense with the use of parts which can be surreptitiously and easily removed without removing the locking pin.

Further objects and advantages of our invention will be apparent as itis better understood from the following description which, taken in connection with theaccompanying drawings, illustrates preferred embodiments thereof.

On the drawings Figure l is a top plan view of a portion of a car and coupler provided with an uncoupling device madelin pursuanceof our invention; Fig. 2 is a front form of the device shown partly in section;

Fig. 7 is a vertical sectional view of the modified form shown in Fig. 6; Fig. 8 is a top plan view of-still another form of the device in position upon a car; Fig. 9 is a front elevation of the device shown in Fig. 8 with parts broken away; Fig. 10 is anend elevation partially in section of the modified form of the invention shown in Figs. 8 and S), the lockin pin of the coupler being in loclcset position; Fig. 11 is a transverse ver tical sectional view of the sleeve member showing the position of the end of the hook when the locking pin of the coupleris in lock-set position; and Fig. 12 is a horizontal sectional view taken on the line 12-49. of Fig. 11. 7

On, the drawings 10 designates a coupler. which may be of any type, having a locking pin 11, and mounted'on a car 12.

The uncoupling device preferably comprises two members 13 and 14. The member 13 consists of a single metallic rod mounted in a substantially horizontal plane in brackets 15 fastened to the car body and having its ends bent at right angles to the main portion of the member and to each other to formthe operating arm or handle '16 and lifting arm 17.

' wherein the sleeye 22 and hook is composed of a hook l8 and a sleeve 19 rigidly secured together and made integral. The axis of the sleeve 19 is disposed at or about right angles to the plane of the hook and is adapted to form a tubular guide and telescopic connection for the end 1e arm 17 when the members are Vmb 1d and in position upon the car. The hook 18 is adapted to fit loosely within the eye of the locking pin and is constructed to pro ide a straight portion 2 0 m en which the locking pin may slide to the right or left as the coupler is moved from central position v-when the cars coupled together travel around acurve. The hook 18 terminates in an upwardly bent end 21 at the end of the straight portion 20 to preventthe hook from being inadvertently removed from the eye of the locking pin.

In at and a hook member is shown 23 are not madeintegral but constitute separate parts pivotally connected together. Except for this diiierence these members are like the sleeve 19 and hook 18 shown in Figs. 1, :2 and 8, and hereinbetore described. The pivotal connection between these .parts is established by providing upon the integral ear 2% having an aperture 25 therein in which an end 26 or" the hook is inserted, the other end 27 of the hook being adapted to be inserted within the eye of the look 'ing pin.

In Figs. 7 and 8 an embodiment of the invention is disclosed wherein the sleeve is provided upon the lifting arm 28 of the member secured to the car end. To this end the arm is made hollow and is provided with slot 29 extending longitudinally thereof from the outer end of the arm inwardly a sufiicient distance to permit a cylindrical element 30, which isloosely fitted within the hollow arm and upon which is formed the ear 31 extending through the slot, to slide longitudinally of the arm the required distance when the arm is moved to raise and lower the locking pin of the coupler, In this embodiment, however, instead of using a hook member to connect the locking pin of the coupler to the member secured to the car end I provide a link 32 which passes through the eye of the locking pinll and through an aperture 33 in the ear 31'ot' the member 30.

In the embodiment of the invention shown in Figs. 8 and 12 the sleeve 34 is provided with a hollow boss 35 extending outwardly at right angles to the axis of the sleeve and preferably located adjacent its outer end. The sleeve 3& its slidably upon the operating arm 17 of the member 13 in the manner described in connection with the sleeve ii in the embodiment of the invention shown in Figs. 1 and 3' and the sleeve 22in the embodiment shown in Figs. i and 5'. i The holpreferably sleeve an low boss is provided at its base with the shoulder 36 which is disposed about the intcrior of the boss and which has recesses 37 formed therein, preferably upon opposite sides of a diameter 1 'irallel to the axis of the sleeve 3st and with an upwardly extending rib 4-2 disposed on each side of each recess. The hook member 38 has an end which fits loosely within the boss 35 arid which is provided with a pair of outwardly disposed lugs 39 which when the parts are in operative position aredisposed above the shoulder 35 and prevent the removal of the end of the hook from the boss. These lugs are preferably disposed in the same plane with the straight portion of -the hook 41 upon which the locking pin of tie coupler is adapted to be slidably mounted. The hook 518 is positioned within the boss 35 of the sleeve by inserting the lugs 39 through the recesses 37 of the shoulder, moving the end inwardly until the lugs clear the top of the ribs 42 and turning it through an angle of 90 and permitting t to fall into operative position as shown on the drawings. The parts are so constructed that when the locking pin is in lock-set position the end of he hook within the boss extends a substantial distance above the base of the boss, providing thereby a slidable connection between the sleeve and hook member which will permit the member 13 to assume itsnormal position when the lockin pin is in look set position so that thcvpin may drop to locking position without changing the position of the member 13. It is apparent that in thus connecting the hook and sleeve members a limited movement ispermitted at all times therebetween' and that a flexible and etlicicnt connection is established.

The operation of the several embodiments of the invention hereinbetore disclosed is substantially the same, and the description of the operation of one of them will apply to the others.

\Vhen' it is desired to uncouple a car provided with an uncoupling device made in pursuance of our invention the handle 16 may be raised, thereby elevating the operating arm and lifting the locking pin 11 by means of the member 14. The sliding con-- nection between the arm 17 and the sleeve 19 of the member 14 will permit this pin,

to be raised substantially vertically, thereby preventing the pin from binding in the aperture of the coupler casting.

It will be manifest from the foregoing that thesliding connection between the two members of the uncoupling device provides for that freedom of movement therebetween .i

which is essential to correspond with the longitudinal movement of the coupler in service.

It will also be apparent that should the coupler be pulled from the car body the body.

sleeve 19 ofthe member 14 will be pulled oil the arm 170i the member 1.3 so that neithenmember will be damaged and the member 13" will not be torn from the car It will may ,be made in the form and construction of the parts and their arrangement without departing. from the spirit and scope of our invention, ii-sacrificing any of its benefits, them-ms hereinbet'ore described being merely preferred embodiments thereof.
